My dehumidifier isn't on the list but I believe maybe it should be. Several times now it gets into a state where it's very loud, abnormally hot and it turns out the compressor is stuck ON even though the fan is not running. Even powering it down (with the button) will not turn off the compressor.

Unplugging it and plugging back in will sometimes fix the problem. Looked into it and it turns out the power relay is getting stuck in the on position. I have to open the dehumidifier completely to get access to the relay and then tap on it with something hard. This has worked to unstick it, at least so far.

I think maybe this relay isn't up to its task. I was curious about replacing it with something similar but couldn't find anything remotely as small for switching 120 VAC mains power.

For reference, my dehumidifer is a Toshiba TDDP7011ES2. The relay in question is a Sanyou SFK-112DMP.

I dunno, maybe this will help someone out there figure out what's going on.
